FOREWORD

This Indian Standard was adopted by the Bureau of Indian Standard!, after the draft finalized by the VkM
Products Sectional Committee had been approved by the Civil Engineering Division Council.

Bamboo mat-veneer composite is manufactured with a combination of bamboo mat and veneer.

In the present scenario, where availability of conventional timber has been reduced to considerable extent this
bamboo mat-veneer composite is expected to find extensive use in future. This standard has been formulated to
guide the manufacturers and users of bamboo mat-veneer composite.

In the preparation of this standard, considerable assistance has been rendered by Indian Plywood Industries
Research and Training Institute, Bangalore.

The composition of the technical committee responsible for the formulation of this standard is given at
Annex D.

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,
observed or calculated, expressing the result of a test of analysis, shall be rounded off in accordance with
IS 2 : 1960 'Rules for rounding off numerical values (revised)'. The number of significant places retained in the-
rounded off value should be the same as that of the specified value in this standard.

BAMBOO MAT-VENEER COMPOSITE FOR GENERAL
PURPOSES — SPECIFICATION

1 SCOPE

This standard covers the method of manufacture and
the requirements of bamboo mat-veneer composites
for general purposes.

2 REFERENCES

The Indian Standards listed in Annex A contain
provisions which through reference in this text,
constitute provision of this standard. At the time of
publication, the editions indicated were valid. All
standards are subject to revision and parties to
agreements based on this standard are encouraged to
investigate the possibility of applying the most recent
editions of the standards indicated in Annex A.

3 TERMINOLOGY

3.1 For the purposes of this standard, the definitions
given in IS 707, IS 6874 and IS 13958 and the
following shall apply.

3.2 Bamboo Mat- Veneer Composite

Panel manufactured with a combination of bamboo
mat and veneer. Bamboo mat can be either as outer
skins or as core/cross-bands. However, the composite
panel shall be a balanced construction on either side
of central ply.

4 MATERIALS

4.1 Bamboo

Any suitable species of bamboo may be used for
making bamboo mat-veneer composite.

4.2 Adhesive

Adhesive for bonding bamboo mat and veneer shall
be of phenolic type conforming to BWR type specified
in IS 848.

4.3 Veneer

Any species of timber may be used for manufacture
of veneers. However, a list of species is given in
Annex B for guidance.

5 MANUFACTURE

5.1 Bamboo Mats

Bamboo mats required for the manufacture of bamboo
mat-veneer composite shall be woven from slivers of
uniform thickness and width. Thickness of slivers shall

be in the range of 0.5 to 0.6 mm and width shall be in
the range of 5 to 1 5 mm. Care shall be taken to exclude
the slivers with epidermal layer.

5.1.1 Prophylactic Treatment

The bamboo mats used for the manufacture of bamboo
mat-veneer composite shall be free from borer
infections. However if transport and/or storage is
inevitable, bamboo mats shall be given prophylactic
treatment as per Group 9 in Table 2 of IS 401.

5.2 Veneer

Veneer shall be either rotary cut or sliced. The veneers
shall be sufficiently smooth to permit an even spread
of adhesive. The quality requirement of veneers shall
conform to the requirements given in Table 1 of IS 303.
However, the maximum number of categories of
defects permitted on the surface of the veneer used for
faces shall be restricted to the requirements laid down
in Table 2 of IS 303. Treatment as specified in 5.2.1
shall be given at the veneer stage.

5.2.1 Treatment

Veneers of non-durable species and sapwood of all
species shall be soaked in 1.25 percent solution of
boric acid or 1.0 percent solution of borax at a
temperature of 85-90°C for a period of 10-40 minutes
depending upon the thickness of the veneers or the
veneers shall be dipped in 2.0 percent solution of boric
acid or 3 percent borax solution for 2 min and block
stacked at least for 2 h. Alternatively, the veneers shall
be soaked at the ambient temperature in a mixture of
0.5 percent solution of Sodium pentachlorophenate
and 1,5 percent of borax in water for a period of 2 min
and then stacked for at least half an hour before drying.

5.3 Thickness

The thickness of all veneers shall be uniform within a
tolerance of 5 percent.

5.4 Joints in Veneers

Veneers that require to be joined to form a ply shall be
spliced before assembly. All joints shall be cut square.
In assembly, joints in veneers running in the same
direction, shall be staggered.

5.5 Permissible Defects

5.5.1 Gaps in cores and crossbands may be permitted
except for 3 ply, provided the width of the gap does

1

IS 14S8S : 1999

not exceed 2 mm in case of 5 kg or more, and much
gaps, if more than one, shall be spaced not less than
80 mm away from each other and are staggered not
less than 50 mm away as between ply, the next pry
having the same grain direction.

5.5.2 Splits in cores and crossbands may be permitted
to an extent of 2 per core or crossbands.

5.5.3 Overlap shall not be permitted.

5.6 Application of Adhesive

Bamboo mats shaUrbe applied with the adhesive either
by soaking or by spreading using mechanical spreader.
However, veneers shall be coated with the adhesive
using mechanical spreader.

5.7 Conditioning of Adhesive Coated Bamboo Mats/
Veneers

Adhesive coated mats/veneers shall be allowed
sufficient length of open assembly time and/or passed
through a band dryer at a temperature ranging between
80° to 90°C to bring down the moisture content of
adhesive coated mats/veneers to 8 to 12 percent.

5.8 Assembly

Adhesive coated and conditioned mats shall be
assembled between two aluminium caul plates whose
surfaces are coated with releasing agent. Care shall
be taken to ensure that (a) on either side of the central
ply same species and thickness is used to get balanced
construction, (b) the grain direction of the outermost
veneer from the centre ply shall be along the larger
dimension of the panel, and (c) when two veneers are
used adjacent to each other the grain direction of the
veneers shall be at right angles to each other.

5.9 Hot Pressing

Assembly of the adhesive coated mats/veneers shall
be hot pressed at not less than 140°C at a specific
pressure of 1.5 N/mm 2 . Hot pressing time shall depend
on the thickness of the board.

5.10 Preservative Treatment

5.10.1 For bamboo matA'eneer composite, preservative
treatment shall be done by incorporating the preser-
vatives like boron (Octoborate or tetraborate) into the
resin before soaking/spreading bamboo mats/veneers
with adhesive as the case may be. The preservative
becomes non-leachable during hot pressing.

5.10.2 Alternatively, the manufactured composite
boards shall be treated with non-leachable type
preservative such as CCA, CCB, or ACC as per
IS 12120.

MYCOLOGICAL TEST

C-l OBJECT

This test is intended to evaluate the resistance of glue
line to attack by micro-organisms.

C-2 PROCEDURE

C-2.1 A flat rectangular dish of enamelled iron, glass
or porcelain (such as a photographic developing dish)
of a minimum depth of SO mm, shall be filled to a
depth of about 25 mm with a layer of sawdust obtained
from the sapwood of perishable timber like semul
(Bombax ceiba) in its natural condition. The sawdust
shall have previously been moistened with water
containing 15 g of sucrose (normally sugar may be
used; but if not available, 30 g of commercial malt
extract may be substituted) to a litre of water so that it
is saturated with moisture, but not so wet that free
water is squeezed out of it by hand pressure. To attain

this condition with dry sawdust, it is usually necessary
to add three times its mass of water.

C-2.2 The sawdust shall then be charged with spores
of the commonly occurring wood destroying fungi and
loosely compacted. The test specimens shall be pressed
down into it so that their upper surfaces are level with
the top of the sawdust layer.

C-2.3 The dish shall then be covered with a sheet of
glass and the edges of the dish sealed against the glass
with modelling clay or a similar suitable material so
that the atmosphere round the test specimens shall
remain saturated with water vapour.

C-2.4 The dish and the contents shall be maintained
at a temperature of 27 ± 2°C for a period of three weeks,
after which the test pieces shall be removed, washed
in water and allowed to dry to a moisture content of
10 to 12 percent in ambient conditions.
